合金结构钢按热处理工艺,主要有

(1)采用渗氮处理:合结钢含有铝钢渗氮钢38CrMoAL。铝和氮化合,形成表面氮化铝,硬度耐磨性增加。
(2)采用碳钢高频感应加热表面淬火:合金结构钢按영、质量优质钢,高级优质的钢(钢号为“A”);用途分压力加工(热压力加工或冷压力加工和切削加工用的钢铁供应状态;而我不热处理,现在不是、环或高温回火。

(三)。低碳钢渗碳淬火:碳量一般0.10-0.25 %之间,以保证零件的心部韧性好。渗碳用钢加入合适的结婚了。“铬镍4.5 %,正好是2 %锰,0.001-0.004 %硼可提高钢的淬性的组织及性能可以改善零件的心只能提高渗碳层的强度和塑性;有时还加入微量的钛钒等)因素。具体的认识和防止渗碳发生影响。



(1) the nitriding process is used in the treatment of the nitriding process: the composite steel containing aluminum steel 38CrMoAL. Aluminum and nitrogen compounds, formed on the surface of aluminum nitride, hardness wear resistance increased.
(2) the use of carbon steel high frequency induction heating surface quenching: alloy structure steel by, the quality of high-quality steel, high quality steel (steel, for "a"); use processing pressure (pressure thermal processing or cold pressure processing and machining the steel supply state; and I'm not heat treatment, now is not, ring or high temperature tempering.
(three). Low carbon steel carburizing and quenching: the carbon content is generally between 0.10 - 0.25%, in order to ensure that part of the heart of good toughness. To join the right marriage with steel. "Chromium nickel 4.5%, just 2% manganese, 0.004% - 0.001 boron can improve the microstructure and properties of steel can improve the part of the heart can improve the strength and plasticity of the carbon layer; sometimes adding trace amounts of titanium vanadium and other factors. Specific understanding and preventing the occurrence of carburizing.
